Abstract: An antenna system 10 for a communications satellite which transmits and receives communications from ground based devices. The system includes an antenna array 16 containing a plurality of feed elements 18 which cooperate to receive or transmit coverage beams arranged in a circular layout at a coverage area in a far-field region proximate the surface of the earth. The feed elements 18 are arranged in a non-circular layout within the antenna array 16. This system further includes a beam forming network 14 for mapping coverage beam signals onto feed signals which drive the antenna array 16. The beam forming network 14 includes a beam forming matrix 28 and a beam connecting network 30. The beam connecting network 30 separates each coverage beam signal into a plurality of component signals weighted to have differing amplitudes from one another. The component signals are delivered to the beam forming matrix 28 which in turn produces corresponding feed signals to drive the antenna array 16 in such a manner as to form feed beams which cooperate to define the coverage beams at the far-field region. The beam connecting network 30 weights the component signals unevenly in order to shift corresponding resultant coverage beams inward or outward until aligned within the coverage area in a circular layout along concentric circles.

Abstract: This invention relates to radio communications and in particular relates
to a method for allocating channels in a radio communications system
having a plurality of bearers in a system which is subject to slow
temporal fading. In radio communications, signals are transmitted at a
particular frequency, in a frequency band or in a number of frequency
bands. Obstacles in a signal path, such as buildings in built-up areas
and hills in rural areas, act as signal scatterers and these, together with
fading, amongst other factors can cause signalling problems whereby
signals may not be communicated on certain channel The present
invention provides a system and method for channel allocation method
for a multi-bearer communications network, with each bearer supporting
a number of channels, wherein after allocation of a channel responsive
to an access request from the available bearers which can provide
access, the maximum number of available slots are left on each bearer,
for a particular level of subscription.

Abstract: A turbine engine (50) including an oil flow path through the low pressure system shaft
(56) which, as compared to at least one known oil flow path, facilitates increasing the rated
torque and life of the low pressure system shaft is described. In one embodiment, the
lubrication opening (78A) in the low pressure shaft is oriented so that with respect to a
plane along which an outer surface of the low pressure shaft substantially extends, the
center axis of the lubrication opening is substantially normal to the plane. As a result of
this configuration, the stress concentration in the low pressure shaft at the location of
the lubrication opening is substantially reduced. In addition, such a lubrication opening
is relatively easy to form as compared to the known, angularly oriented lubrication
shaft. Further, the lubrication opening in the present configuration can have a larger
diameter than the known angularly oriented lubrication opening due to the reduced stress
concentration, and such a larger lubrication opening facilitates more free flow of
lubrication through the opening to the differential bearing.

Abstract: A fuel control system for a gas turbine engine having a
staged combustor includes apparatus and methods to
operate the combustor during pilot operation, staged
operation, and transition between the two modes of
operation. Various construction details are developed
which provide a fuel control having a switch with built

between operating modes. In one embodiment, the
combustor is switched from pilot to staged operation at a
thrust level greater than the thrust level at which the
combustor is switched from staged to pilot operation.
During transitions between operating modes, the changes
in fuel flows are limited by a plurality of rate limits
to prevent combustor fuel spikes and blow-outs from
occurring. During engine starts, the fuel lines to the
main combustor are pre-filled to provide responsiveness
during the transition from pilot to staged operation.

Abstract: A power wheelchair includes an anti-tip assembly extending from the frame.
The anti-tip assembly includes a plate (44) secured to the frame via a dampening
mechanism (46). A first arm (52) extends from the plate (44) and is mounted thereto
for a limited amount of relative movement. A ground engaging wheel (72) disposed

to tip, anti-tip or resistive forces are generated initially by the biasing spring (68).
This resisting force continues in a linear fashion until relative movement between the
arm (52) and the plate (44) ceases. Thereafter, further resistive forces are provided
by the dampener (46) as movement of the plate (44) toward the frame is resisted in
a linear fashion by the dampener (46).
